T aZZ whom it may concern: cept through its central portion, within which Be it known that I, JAMES M. CHAMBERS, is placed the upper and open end of the firea citizen of the United States, residing at the box or heater a, an annular cylindrical space city of St. Louis, State of Missouri, have in- 0 being left between the heater CL and the cylvented a certain new and useful Improved inder or drum 1). Apparatus for Heating and Drying Barrels or Surrounding the cylinder or drum 1), at a Casks, of which the following is a full, clear, suitable distance therefrom and concentric and exact description. therewith, is an outer drum or casing d, be-

My invention relates to theheating and drytween which and the cylinder or drum 1) is [0 ing of barrels or casks preparatory to the formed an annular space or chamber e,which 6o hooping and finishing of same, and is an imis closed at both ends bythe upper and lower provement on that for which Letters Patent rings or framing f, respectively. Through have been granted to me bearing date Septhe wall of the cylinder or drum 1), near its tember '7, 1886, No. 348,888, for improved aplower end, are openings 1), which establish I 5 paratus for heating and drying barrels or communication between the annular spaces 0 casks. and e, and through the wall of the outer drum My invention has for its object to eifect a or casing d, near its upper end, are openings more thorough drying of the barrel or cask, d into the external air. and at the same time reduce the consumption Beneath the annular space 0 the barrel or 20 of fuel by prolonging the circulation of the cask g to be dried is placed in an upright poheated gases from around the barrel and to sition on a platform 'h, to each side of which direct their escape into the atmosphere toare secured the lower ends of rods 1', which ward the upper part of the apparatus instead pass freely through lugs j on the circumferof at the base thereof, as in my said patent. ence of the rings or framing f, the rods 2' be- 2 5 It consists in a combination and arrangeing united above the upper ring f by crossment of apparatus whereby the barrel or cask bars t", which are secured together at a suitis raised into position around the heater, the able distance apart over the center of the upheat from which is caused to circulate interper ring f by a rivet and intervening washer nally and externally around the barrel,which F, or by a bolt and nut or otherwise, as found 0 is inclosed by a cylinder or drum, through the most convenient. The cross-head 1" thus conlower part of which the heated gases pass upstructed, carrying the platform 72, is susward through an annular space surrounded pended, preferably at the center, from a pulby an outer drum or casing, and from the upley-block it, having a single sheave Z, under per part of the latter into the atmosphere. which passes a rope or chain m, fixed at one 3 5 On the accompanying drawings, Figure 1 end to the ceiling or analogous support,wh ile representsasectional elevation,partly broken its other end passes over one or more overaway, of the apparatus comprising myinvcnhead pulleys n, and terminates in a countertion, with the barrel or, cask lowered away balance-weight 0, which hangs within reach from the heater; Fig. 2, a similar view with of the operator. 40 the barrel in the raised position for being Fuel is fed to the heater a and its grate p 0 heated and dried; and Fig. 3, a plan thereof through the central opening in the upper ring to a reduced scale, omitting the overhead pulor framing f and'open end of the heater to,

The lower ends of the bars 8 are secured to the upper side of a flanged basering to, on which the platform 72 when lowered, is support-ed. The central upright webs s of the bars 8 engage in slots 8 formed in the edge of the platform 72, which is thereby maintained while being raised and lowered, with the cask gin the properposition beneath the heater a. The fire being lighted in the heater a, and the barrel or cask g, with the platform It and other parts of the apparatus in the positions shown in Fig. 1, on pulling down the counterbalance-weight 0 and rope or chain m the platform h, with the barrel g, will be raised by the cross-head "t" and rods 1', and the barrel g, passing through the lower open end of the cylinder or drum 1) and entering and occupying the annular space c,will surround the heater a, which in this position of the barrel 9 projects through a central hole therefor in the platform h, and the heat from the heater a circulating in the annular space 0 acts upon the outside as well as the inside of the barrel g, so as to thoroughly dry the latter.

In raising the barrel 9 to be heated as described the lower end of the annular space 0 is closed by the platform h coming in contact with the lower edge of a projecting ring 3, formed on the under side of the lower framing f around the open end of the cylinder or drum 1), whereby the heated gases from the annular space 0 are prevented from escaping thereat into the air and compelled to pass through the lower openings 1) of the drum 1 into the annular space 6, and circulating upward through the latter finally pass out through the openings d of the outer casing d into the external atmosphere, by which means the heated gases, being prevented from escaping too rapidly from the space 0, their full effect is utilized for drying the barrel g, and consequently less fuel is required than when the gases are allowed to escape directly from the space 0 into the air, as in the apparatus described in my said Letters Patent. Another advantage of this arrangement is that the escape of the gases is effected at a convenient height from the operator, instead of in proximity thereto, as heretofore.

I claim as my invention In apparatus for heating and drying barrels, the combination of the heater a, cylinder or drum 6, having openings 1) near its lower end and forming annular space 0, Outer drum or casing d, having openings d near its upper end and forming annular space (2, said drums being carried by framing f, with platform It for carrying the barrel g, andmeans for raising and lowering said platform, sub: stantially as shown, and for the purpose described.

In testimony whereof I atfix my signature, in presence of two witnesses, this 2 lth day of October, 1888.
